Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier if you already pay Gemini. B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for open-source model APIs. The default in this space.
